Bait applicator

ABSTRACT

A variable length bait applicator allows bait to be placed or held in remote locations. Rods are attached to one another to attain a desired length by inserting a securing extension in a rod first end into an open second end in a second rod. A bait holder is secured to the rod(s) by inserting a rod securing extension into an access opening in the bait holder first end. The bait holder is provided with a splined pin or shaft extension having protrusions and retainers on a second end. An access opening in the bait holder allows a snap lock on the securing extension that is secured over a locking protrusion on the bait holder to be disengaged.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] A variable length bait applicator positions a bait holder in remote locations where it can be monitored or removed at will.

[0003] 2. Description of Related Art

[0004] It is a common practice to toss bait under cabinets, in crawl spaces, attics, in wall voids, etc. without checking on or removing the bait. Such disposal of bait can lead to infestations such as grain insects, fabric pests, and numerous other parasitic insects as well as the possible poisoning of non-target animals and children. The removal and extermination of pests by traps and poisons for rodents, termites, etc. is old and common. N. Su, U.S. Pat. No. 6,397,516, issued 4 Jun. 2002 and R. Legerle et al, U.S. Pat.

SUMMARY OF THE INVENTION

[0005] A bait holder or hanger has an extension on one end that secures bait, having a hole in it, to the bait holder. The bait holder is attached to a rod used to insert and remove bait in hard to reach areas and inaccessible voids, such as attics, crawl spaces, and drop ceilings. The device allows the material or bait to be monitored, replaced and removed as necessary or desireable. The rod(s) and bait holder can be permanently or removably secured to each other using snap locks and matching locking protrusions. Using rods attached end to end a long reach can be attained by inserting securing extensions on one rod first end into an open rod second end of a second and subsequent rods.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016]FIG. 1 is a perspective view of the bait applicator 1 consisting of two rods 2 joined together with a bait holder 3 secured to a bait 4.

[0017]FIG. 2 is an exploded perspective view of two rods end connectors. The rods 2 are molded 8 elongated extensions. One first end has a securing extension 5 with resilient snap locks that extend outwardly. The second end has an open end 7 that the securing extension and resilient snap lock fit into. A securing hole 9 is provided that can be used to attach the rods to a structure such as a cabinet, pipe, wall, floor or other object to secure it in position so that it cannot be removed accidentally or by a pet or child during treatment.

[0018]FIG. 3 is a sectional side view of rod ends secured together. The securing extension 5 of the first rod is inserted all the way into the open end of the second rod. The second rod has a locking protrusion 11 over which the protrusions 6 of the snap lock fit to permanently secure the two rods together.

[0019]FIG. 4 is a perspective view of a first bait holder 3 with a bait 4 attached to it. The bait holder has an outside perimeter essentially the same as the outside perimeter of the rods 2. The first end of the bait holder has a rod access opening 7, the same as the open second end of a rod 2, for securing it to a first rod end securing extension 5. An elongated bait holder access opening 10 provides access to the interior of the bait holder.

[0020]FIG. 5 is an exploded perspective view of the bait holder. The second end of the bait holder has integral therewith or attached thereto a pin 13 that is provided with protrusions such as splines that extend outwardly therefrom. The bait 4 has a bait hole 15 extending therethrough. The bait hole 15 preferably has a diameter that is smaller than the protrusions 14 of the pin 13. The bait is pressed onto the protrusions of the pin to secure the bait on the bait holder.

[0021]FIG. 6 is a sectional side view of the bait holder 3 and bait 4 secured to one end of a rod 2. The bait holder has a locking protrusion 12 that extends into the rod access opening. The snap lock 6 of the securing extension 5 snaps over the locking protrusion 12 to secure the bait holder to the rod 2. Unlike the locking shown between the snap lock 6 and locking protrusion 11 of FIG. 3, the holder access opening 10 provides access to the snap lock 6. Since the bait holder lower side has no locking protrusion, only the upper snap lock 6 secures the bait holder 3 onto the rod 2. By using the bait holder access opening to press on the top snap lock 6, the snap lock 6 can be forced inwardly and beyond the locking protrusion 12. In this position, the bait holder 3 can be pulled away from the rod. This makes the rod and/or bait holder reusable with other rods and/or bait holders. The bait holder 3 can be designed to be permanently connected to a rod 2 as shown in FIG. 3.

[0022]FIG. 7 is a perspective view of a second bait holder 30 with bait 4 attached. The bait holder 30 has an access opening 31 with a retainer 40 having an outer opening 41.

[0023]FIG. 8 is an exploded side view of the bait holder of FIG. 7. FIG. 9 is a partial sectional side view of the bait holder of FIG. 8 on a rod. The bait holder 30 second end is provided with a shaft extension 33 that extends further than the bait hole 15. Short protrusions 34 extend outwardly from the shaft extension 33. The protrusions 34 on the extension have an outward extent that is preferably but not necessarily greater than the diameter of the bait hole 15. Pressing the extension 33 into the bait 4 results in the protrusions tightly holding the bait in position. The shaft extension outer end is provided with a locking knob 35 that has a diameter greater than that of the shaft extension 33. The retainer 40 has a central outer opening 41, that has a diameter that is essentially the same as that of the locking knob 35, and a central inner opening 42, that has a diameter that is smaller than the diameter of the locking knob 35. The different diameters form a retainer lip 43, shown within a circle in FIG. 9, and shown enlarged in FIG. 10. By pressing the retainer 40 over the extension locking knob 35, the locking knob is forced through the inner opening 42 and into the outer opening 41. When the locking knob 35 is passed through the inner opening 42 it expands into the outer opening 41 and presses against the retainer lip 43 to lock the retainer 40 and bait 4 onto the bait holder 30. As with the bait holder 3 access opening 10, the access opening 31 permits the rod 2 snap lock 6 to be removably secured to the bait holder 30. As with the locking protrusion 12 of the first bait holder 3, a locking protrusion 32 secures the snap lock 6 to the rod 2 adjacent to access opening 31.
